Garrett Reid, son of Philadelphia Eagles head football coach Andy Reid, was found dead Sunday in his room at the Eagles training camp at Lehigh University.
"This is a tough morning for all of us in the Eagles family," the team's General Manager Howie Roseman said, holding back tears as he announced the news to reporters.
"Garrett grew up with this team, and this makes this news even harder for us to process."
Training camp will continue, he said. Offensive coordinator Marty Mornhinweg and defensive coordinator Juan Castillo will oversee the team until Andy Reid returns, according to the team.
Lurie said Reid, while grieving, regrets being away from the team.
"I expect Andy to be coaching this week; in fact, I know he feels that way and he is very, very focused on both his family and his profession," Lurie said.
Players were informed of the death before the team's workout, in a huddle with Lurie.
Quarterback Michael Vick was among many players and staff extending their condolences to Reid and his family Sunday.
"He's (Andy Reid) been a rock for us and a big teddy bear for us so we're going to lean on him and we're going to be there for him and we're going to stay storng for him until he comes back and lead us on," Vick said.
There were no signs of suspicious activities in Garrett Reid's death, authorities said.
Reid, 29, was assisting the strength and conditioning staff at training camp, the team said. He was a guest of his father, not part of the staff, a team spokesman said.
An investigation is under way.
